Systems and methods for remote-initiated device backup

ABSTRACT

A system described herein may provide a technique for the remote backup of a User Equipment (“UE”). An initiating device may be registered as being associated with the UE, and may initiate remote backups of the UE, without requiring user interaction at the UE. Different network backup policies may be specified in the request, such as a “Wi-Fi only” network backup request. If the UE is in a “lost” mode, a “damaged” mode, and/or is otherwise unusable or inaccessible, the specified network backup policy may be overridden, to ensure that the UE is backed up and the relevant device data may be recovered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

UEs, such as mobile telephones, tablets, and/or other devices, may store user information, such as contacts, pictures, videos, messages, call histories, preferences, and/or other information. However, UEs may become lost, stolen, damaged, and/or otherwise inoperable by the user. A backup may be utilized to restore user information when a UE becomes inoperable, lost, damaged, and/or stolen.

Embodiments described herein provide for the remote initiation of a backup of a UE, without requiring an action to be performed by the UE to be backed up. This remote backup may be useful, for example, in situations where a customer is looking to upgrade to a different UE, the original UE has been lost, damaged, or stolen, or is otherwise inaccessible to a user associated with the UE (e.g., a rightful owner of the UE). Further, the remote backup, in accordance with some embodiments, may be useful if a user associated with the UE to be backed up (referred to herein as a “Backup UE”) is not technically savvy, is handicapped, and/or is otherwise unable to initiate the backup, but a user associated with another UE (referred to herein as an “Initiating UE”) is able to initiate the backup.

As shown in FIG. 1, for example, Backup UE 101 and Initiating UE 103 may register with Remote Backup System 105. In the examples illustrated herein, Backup UE 101 may be a mobile telephone, and Initiating UE 103 may be a laptop computer. In practice, Backup UE 101 and/or Initiating UE 103 may both be mobile telephones, or may both be laptop computers. In some embodiments, Backup UE 101, Initiating UE 103, or both, may be or include some other type of device. Examples of registering Backup UE 101 and Initiating UE 103 are described below with respect to FIGS. 2 and 3, respectively. Briefly, this registration may be used to indicate or instantiate remote backup functionality for Backup UE 101, and may further be used to indicate that Initiating UE 103 is an authorized initiating UE for the remote backup of Backup UE 101.

As shown, Initiating UE 103 may request (at 102) a backup of Backup UE 101. For example, Remote Backup System 105 may be a web-accessible resource (e.g., accessible via the Internet), and Initiating UE 103 may execute an application that is configured to communicate with Remote Backup System 105. Additionally, or alternatively, Initiating UE 103 may communicate with Remote Backup System 105 via a web portal (e.g., using a Uniform Resource Locator (“URL”) or other suitable identifier or locator associated with Remote Backup System 105). Additionally, or alternatively, Initiating UE 103 may communicate with Remote Backup System 105 via an application programming interface (“API”) and/or some other suitable interface or communication pathway.

The backup request may include an identifier of Backup UE 101 (e.g., a Mobile Directory Number (“MDN”), an International Mobile Subscriber Identity (“IMSI”) value, an International Mobile Station Equipment Identity (“IMEI”) value, and/or some other suitable identifier). In some embodiments, the backup request may include authentication information associated with Initiating UE 103, such as a user name and password, an authentication token, etc. As described below, Initiating UE 103 may receive or maintain the identifier of Backup UE 101, the authentication token, and/or other information during a registration process with Remote Backup System 105.

In some embodiments, the backup request may include a selection of types of data (e.g., contact information, recent calls, photographs, videos, music, etc.) to backup. For example, as described below, Initiating UE 103 may present a GUI that provides options to select what types of data, associated with Backup UE 101, to backup. In some embodiments, a user associated with Backup UE 101 may indicate what types of data to backup. For example, prior to the request (at 102) from Initiating UE 103, such as during a registration process, Remote Backup System 105 may receive a pre-selection of types of data to backup, once a backup request is actually received (e.g., from Initiating UE 103).

In some embodiments, the backup request may include a network backup policy and/or other parameters regarding particular networks or network types via which the backup is permitted. For example, the network backup policy may specify that the backup may only occur when Backup UE 101 is connected to a Wi-Fi network, and/or to a particular Wi-Fi network (e.g., a Wi-Fi network having a specified Service Set Identifier (“SSID”)). As another example, the network backup policy may specify that the backup may occur only when Backup UE 101 is not roaming (e.g., is connected to a “home” or “non-roaming” wireless network). As yet another example, the network backup policy may specify different parameters for different times of day, days of the week, etc. For example, the network backup policy may specify that the backup may only be performed when Backup UE 101 is connected to a Wi-Fi network between 9:00 AM and 5:00 PM, but may be performed regardless of network type between 5:01 PM and 8:59 AM.

In some embodiments, the network backup policy may specify different parameters for whether Backup UE 101 is in a “lost” mode. The network backup policy may specify, for example, that if Backup UE 101 is not in the “lost” mode, then Backup UE 101 may only backup while connected to Wi-Fi. The network policy may further specify that if Backup UE 101 is in the “lost” mode, then Backup UE 101 may backup while connected to any type of network.

In some embodiments, Backup UE 101 may be a device that supports a “lost” mode, in which Initiating UE 103 or some other authorized device may designate Backup UE 101 as being lost (e.g., out of the possession of an owner of Backup UE 101). In “lost” mode, Backup UE 101 may require user authentication (e.g., a Personal Identification Number (“PIN”) code, user name and password, biometric authentication, and/or some other suitable authentication) before full functionality is restored. For example, if Backup UE 101 is a mobile telephone, the “lost” mode may restrict all functionality except for emergency calls. If Backup UE 101 is a laptop computer or some other device, the “lost” mode may restrict all functionality until full functionality is restored. In some embodiments, the “lost” mode may require additional authentication as compared to a standard “lock” screen or “login” screen associated with Backup UE 101. For example, the additional authentication may include answering security questions via a web portal, resetting a password associated with Backup UE 101, providing a two-factor authentication code from another authorized device, and/or other suitable additional authentication measures. In some embodiments, the “lost” mode may be initiated by Initiating UE 103 and/or some other device that is authorized to initiate the “lost” mode. Backup UE 101 may, for example, receive a command, notification, instruction, etc., from Remote Backup System 105 or some other device or system to enter the “lost” mode, and may thus enter the “lost” mode without user input at Backup UE 101.

In some embodiments, the network backup policy may specify a maximum throughput or amount of data to backup when connected to a particular type of network (e.g., a licensed wireless network, such as a Long-Term Evolution (“LTE”) network, a Fifth Generation (“5G”) network, a Third Generation (“3G”) network, a Code Division Multiplex Access (“CDMA”) network (e.g., a CDMA 2000 1x network), and/or some other licensed wireless network). In some embodiments, the network backup policy may include conditions based on a subscription associated with Backup UE 101. For example, the network backup policy may specify that if the size of the backup would exceed a data allotment associated with a subscription associated with Backup UE 101, then the backup may only be performed over a Wi-Fi network.

As further shown in FIG. 3, Remote Backup System 105 may authenticate (at 104) the backup request from Initiating UE 103. For example, Remote Backup System 105 may verify authentication credentials established or provided during registration. As discussed below, these authentication credentials may include a user name and password, an authentication token, and/or some other suitable set of authentication credentials.

In some embodiments, Remote Backup System 105 may obtain (at 106) additional information associated with Backup UE 101. For example, Remote Backup System 105 may obtain the additional information from UE Information Repository 107, which may be a device or system associated with a core of a wireless network (e.g., a LTE core network, a 5G core network, etc.). For example, UE Information Repository 107 may be, or may include, a Home Subscriber Server (“HSS”), a Unified Data Management function (“UDM”), or some other suitable device. In some embodiments, UE Information Repository 107 may be accessed via a Service Capability Exposure Function (“SCEF”) associated with the core network, a Network Exposure Function (“NEF”) associated with the core network, and/or some other suitable device or system. In some embodiments, UE Information Repository 107 may maintain information indicating an amount of data (e.g., in Megabytes, Gigabytes, etc.) remaining on a subscription associated with Backup UE 101, and/or other subscription-related information.

Remote Backup System 105 may further instruct (at 108) Backup UE 101 to perform a backup. For example, the instruction may include selected types of data to backup (e.g., as indicated in the backup request). In some embodiments, Backup UE 101 may have been pre-configured (e.g., during a registration process) of which types of data or particular items to back up. In some embodiments, the instruction (received at 106) may include the network backup policy, as discussed above. In some embodiments, the instruction may indicate the amount of data remaining on a subscription associated with Backup UE 101, and/or other suitable information.

In some embodiments, the instruction may include a URL, Internet Protocol (“IP”) address, and/or other identifier or locator associated with Backup Data Repository 109. In some embodiments, Backup UE 101 may be pre-configured with the identifier or locator associated with Backup Data Repository 109. For example, an operating system or backup application executing on Backup UE 101 may be configured with the identifier or locator of Backup Data Repository 109.

In some embodiments, the instruction may be sent as a notification, such as a “silent” notification. For example, Backup UE 101 may implement (e.g., at the operating system level) a notification channel via which Backup UE 101 may receive instructions or messages that are not explicitly presented to a user of Backup UE 101. As one example, a notification related to a messaging application executing on Backup UE 101 may be considered a “non-silent” or “regular” notification. In some embodiments, the notification may include a token or some other suitable authentication mechanism, via which Backup UE 101 may authenticate the backup instruction.

In some embodiments, Backup UE 101 may have been configured (e.g., during a registration process) to present a “non-silent” or “regular” notification (e.g., a visual notification on a display screen) when the silent notification is received (at 108), indicating to a user of Backup UE 101 that a backup has been initiated. In some embodiments, this notification may include options to change what items or types of data are to be backed up, delay or reschedule the backup, cancel the backup, modify the network backup policy, and/or otherwise modify parameters of the backup.

Backup UE 101 may proceed to back up (at 110) the requested data. For example, Backup UE 101 may provide the requested data to Backup Data Repository 109 in accordance with the network backup policy. In some embodiments, Backup UE 101 may calculate the size of the backup prior to outputting the backup data, and may compare this calculated size to the remaining amount of data associated with the subscription of Backup UE 101 (e.g., if indicated in the network backup policy). As another example, Backup UE 101 may determine whether Backup UE 101 is in a “lost” mode, and may utilize one or more specific types of networks based on whether Backup UE 101 is in the “lost” mode and whether the network backup policy specifies different params for whether Backup UE 101 is in the “lost” mode.

Backup Data Repository 109 may receive and store (at 112) the backup data for later retrieval. While not described in detail herein, Backup Data Repository 109 may perform suitable authentication techniques prior to providing the backup data for later retrieval (e.g., restoring the backup on Backup UE 101 or another suitable device).

As referred to above, FIG. 2 illustrates an example registration of Backup UE 101. As shown, Backup UE 101 may initialize (at 202) a remote backup application. In some embodiments, the remote backup application may be installed (e.g., “pre-loaded”) on Backup UE 101 by a manufacturer or vendor (e.g., prior to receipt by a user of Backup UE 101). In some embodiments, the remote backup application may be part of the native functionality of an operating system or firmware of Backup UE 101. In some embodiments, the remote backup application may be installed by a user of Backup UE 101. For example, Backup UE 101 may install the remote backup application through an application “store.” “Initializing” the remote backup application may include powering on or performing an initial setup process of UE 101 (e.g., where part of the initial setup includes initializing the remote backup application), and/or receiving a selection to open or execute the remote backup application.

Backup UE 101 may further output (at 204) a registration request to Remote Backup System 105. For example, the remote backup application may be configured with a URL, IP address, or other locator or identifier associated with Remote Backup System 105. The registration request may be sent after receiving a request (e.g., from a user of Backup UE 101, via the remote backup application) to register for the remote backup techniques described herein. In some embodiments, the registration request may include a device identifier associated with Backup UE 101, such as an IMSI, IMEI, MDN, etc. In some embodiments, the device identifier may be derived from a device identifier, such as a hash or other operation performed on the IMSI, IMEI, MDN, and/or other suitable value.

In some embodiments, the registration request may include one or more network backup policies. For example, in some embodiments, the network backup policies specified during registration (at 204) may override a network backup policy specified during a backup request (e.g., at 102). For example, the registration request may specify that when Backup UE 101 is in “lost” mode, the backup may occur via any network or type of network. Thus, even if a backup request does not indicate that a particular type of network is permissible (e.g., a LTE network) for the backup, Backup UE 101 may nonetheless perform the backup via the particular type of network if Backup UE 101 is in “lost” mode.

Remote Backup System 105 may authenticate and register (at 206) Backup UE 101 based on receiving the registration request. For example, Remote Backup System 105 may authenticate Backup UE 101 based on the received device identifier. In some embodiments, Remote Backup System 105 may communicate with an authentication system and/or with UE Information Repository 107 (e.g., an HSS, UDM, etc. of a core network and/or some other suitable device or system) in order to authenticate Backup UE 101.

As further shown, Remote Backup System 105 may communicate with UE Information Repository 107 to obtain (at 208) information indicating an amount of storage resources allocated for backups associated with Backup UE 101. For example, UE Information Repository 107 may maintain information indicating the amount of storage resources (e.g., associated with Backup Data Repository 109) that has been provisioned, or is authorized to be provisioned, for Backup UE 101. In some embodiments, different UEs may be associated with different subscriptions or policies that indicate different amounts of storage that may be used for backups. In some embodiments, the amount may change based on the actual capacity and/or utilization of Backup Data Repository 109. For example, if Backup Data Repository 109 is relatively heavily utilized, less storage resources may be available for Backup UE 101 than if Backup Data Repository 109 is less heavily utilized. In some embodiments, Remote Backup System 105 may provision (at 210), or cause to be provisioned, the amount of storage resources, of Backup Data Repository 109, for Backup UE 101.

As also referred to above, FIG. 3 illustrates an example registration of Initiating UE 103. As shown, Initiating UE 103 may register (at 302) as an initiating UE for Backup UE 101. For example, Initiating UE 103 may provide an identifier of Backup UE 101, such as an MDN and/or some other suitable identifier, along with a request to register as an initiating UE for Backup UE 101. Remote Backup System 105 may authenticate (at 304) Initiating UE 103. For example, Remote Backup System 105 may determine whether Initiating UE 103 is associated with a same account as Backup UE 101. As another example, Remote Backup System 105 may confirm and/or request (at 306) the authentication of Initiating UE 103. For example, Remote Backup System 105 may output a notification or other suitable prompt to Backup UE 101, such as “Did you just register a new initiating device?” Once authenticated (at 304 and/or 306), Remote Backup System 105 may output (at 308) a confirmation and/or a token to Initiating UE 103. As noted above, this token may be provided by Initiating UE 103 during subsequent requests (e.g., at 102) to back up Backup UE 101.

FIG. 4 illustrates an example GUI 401, which may be displayed to select types of data to backup and/or a network backup policy. GUI 401 may, for example, be presented via Initiating UE 103 (e.g., as part of the request to initiate a backup) and/or via Backup UE 101 (e.g., as a preference selection for future backups). As shown in FIG. 4, different types of data, such as contacts, photos, videos, music, documents, messages, and/or call history, may be selectable.

Further, GUI 401 may provide various options to specify a network backup policy. In the example shown, these options may include a Wi-Fi Only option, a Wi-Fi Only (Specific networks) option (e.g., where a user may further specify particular Wi-Fi networks), or a Wi-Fi and Mobile Networks option. As further shown here, an “Unrestricted backups in Lost mode” option may be provided, which may specify special behavior when Backup UE 101 is in “lost” mode. In some embodiments, these options may be presented in a different manner, and/or other options may be presented via GUI 401.

FIGS. 5 and 6 illustrate example embodiments, in which a network backup policy may be overridden when Backup UE 101 is in “lost” mode. For example, FIG. 5 illustrates an example in which a network backup policy, specified by Initiating UE 103, may be overridden when Backup UE 101 is in “lost” mode, and FIG. 6 illustrates an example in which a network backup policy, specified by Backup UE 101 (e.g., during registration) may be overridden when Backup UE 101 is in “lost” mode. Some of the operations shown in these figures may be the same as, or similar to, operations described above. Therefore, these operations are not discussed in detail below for the sake of brevity. Further, some of the operations described above (e.g., authentication, provisioning, etc.) are not shown in these figures for the sake of brevity. In practice, some or all of these operations may be performed in conjunction with the operations shown in FIGS. 5 and 6.

As shown in FIG. 5, for example, Backup UE 101 may receive (at 502) an instruction to enter “lost” mode. For example, Backup UE 101 may receive the instruction from Initiating UE 103, Remote Backup System 105, and/or some other authorized device or system. For example, Backup UE 101 may implement an API or other suitable mechanism whereby Backup UE 101 may receive and authenticate the instruction, and may accordingly enter the “lost” mode. As discussed above, the “lost” mode may include limited functionality at Backup UE 101, such as the inability to access applications, make non-emergency telephone calls, etc. before performing an enhanced unlock process, which may include authentication procedures beyond a normal unlock process. For example, the enhanced unlock process may involve an authentication server, and may include verification that Backup UE 101 is back in the possession of a rightful owner of Backup UE 101.

At some point after Backup UE 101 enters the “lost” mode, Initiating UE 103 may request (at 504) a backup of Backup UE 101. In this example, the request may specify a network backup policy, which may indicate that the backup may only be performed via a Wi-Fi network. For example, a user associated with Initiating UE 103 may not be aware that Backup UE 101 is in “lost” mode, the request may be an automated request, the request may inadvertently include the network backup policy, etc.

Remote Backup System 105 may output (at 506) the backup instruction, including the “Wi-Fi only” network backup policy. As discussed above, the backup instruction may be sent via a “silent” notification and/or some other suitable messaging technique.

Backup UE 101 may receive the instruction, including the “Wi-Fi only” network backup policy, and may override (at 508) the indicated network backup policy based on being in “lost” mode. For example, as discussed above, Backup UE 101 may execute a backup application, and/or an operating system associated with Backup UE 101 may be configured with backup functionality, via which Backup UE 101 may receive the backup instruction and back up data accordingly. In some embodiments, the backup application and/or the operating system of Backup UE 101 may communicate via an API, via which the operating system of Backup UE 101 may indicate to the backup application that Backup UE 101 is in “lost” mode. In some embodiments, Backup UE 101 may override the indicated network backup policy based on a selection of an option (e.g., the “Unrestricted backups in Lost mode” option shown in FIG. 4) to override a network backup policy, indicated in a backup request, when Backup UE 101 is in “lost” mode.

Based on overriding the “Wi-Fi only” network backup policy, Backup UE 101 may back up (at 510) device data over Mobile Network 501 (e.g., a type of network other than a Wi-Fi network). “Mobile” Network 501 may refer to, for example, a LTE network, a 5G network, and/or some other type of network that utilizes licensed communications. Mobile Network 501 may include, in some embodiments, a cellular wireless telecommunications network.

In some embodiments, when in “lost” mode, Backup UE 101 may initiate a backup without receiving a notification from Remote Backup System 105. For example, either immediately upon entering into “lost” mode, or after a threshold amount of time, Backup UE 101 may initiate the backup. In some embodiments, Backup UE 101 may ignore a configured network backup policy when performing the backup when in “lost” mode (e.g., may back up data via Mobile Network 501, even if Backup UE 101 has been configured with a “Wi-Fi only” network backup policy).

As shown in FIG. 6, Backup UE 101 may register (at 602) and/or otherwise be configured with a “Wi-Fi only” network backup policy. In some embodiments, this registration may include the omission of a selection of an option to override network backup policies while in “lost” mode. For example, the “Unrestricted backups in Lost mode” option shown in FIG. 4 may not be selected at Backup UE 101 during a registration or configuration process.

At some subsequent time, Backup UE 101 may receive (at 604) an instruction to enter “lost” mode, and may accordingly enter “lost” mode. Initiating UE 103 may subsequently output (at 606) a request for a backup of Backup UE 101, and Remote Backup System 105 may output (at 608) a backup instruction to Backup UE 101. Operations performed in this example may be independent of a network backup policy indicated in the request, and/or the request may not indicate a network backup policy.

Backup UE 101 may receive the request and, based on being in “lost” mode, may override (at 610) the configured “Wi-Fi only” network backup policy. This overriding may be useful in scenarios where Backup UE 101 is permanently lost. In some embodiments, Backup UE 101 may override the configured network backup policy only after having been in “lost” mode for a threshold period of time. For example, if Backup UE 101 has been in “lost” mode for at least 24 hours, Backup UE 101 may override (at 610) the configured network backup policy, whereas if Backup UE 101 has been in “lost” mode for less than 24 hours, Backup UE 101 may adhere to the registered network backup policy. Under this approach, deference may be given to the configured network backup policy, but if Backup UE 101 is permanently lost, the data stored on Backup UE 101 may be effectively backed up (at 612) via Mobile Network 501 for later retrieval and restoration on a new UE.

In some embodiments, if Backup UE 101 is in “lost” mode, Backup UE 101 may notify Remote Backup System 105 that Backup UE 101 is in “lost” mode. Remote Backup System 105 may communicate with a charging system associated with Mobile Network 501, to indicate that Backup UE 101 is in “lost” mode and is backing up data via Mobile Network 501. Based on this communication, the charging system associated with Mobile Network 501 may reduce or eliminate data charges associated with the backup. In some embodiments, Remote Backup System 105 may provision additional storage space in Backup Data Repository 109, and/or may instruct Backup Data Repository 109 to permit the backup from Backup UE 101 to exceed an initially provisioned amount of storage space based on being in “lost” mode. In this manner, robust solutions may be provided for users who have lost their devices and have not necessarily prepared for such an occurrence.

While examples of how a “lost” mode may be overridden are provided above, in practice, other variations are possible. For example, when entering “lost” mode, Backup UE 101 may notify Remote Backup System 105 that Backup UE 101 is in “lost” mode. For example, the backup application executing on Backup UE 101 may receive, from an operating system of Backup UE 101, an indication that Backup UE 101 has been placed in “lost” mode, and may communicate with Remote Backup System 105 to indicate that Backup UE 101 is in “lost” mode. In such a scenario, Remote Backup System 105 may override a network backup policy indicated by Initiating UE 103 (e.g., in a backup request), and may provide a different network backup policy (e.g., an unrestricted network backup policy) to Backup UE 101 when providing a backup instruction to Backup UE 101.

FIG. 7 illustrates an example embodiment, in which backup data, associated with Backup UE 101, is automatically restored to a Replacement UE 701 when Backup UE 101 has been lost, damaged, upgraded, and/or otherwise replaced. For example, as shown, Backup Data Repository 109 may receive (at 702) backup data from UE 101. The backup data may be received based on requests from an authorized Initiating UE 103, may be received automatically (e.g., as part of a periodic or intermittent backup procedure), and/or may be received in some other fashion.

At some point, Backup UE 101 may be replaced by Replacement UE 701. For example, Backup UE 101 may be lost, damaged, or otherwise unusable. As another example, a user associated with Backup UE 101 may opt to upgrade devices, or select a different device. As such, Replacement UE 701 may be initialized and/or provisioned (at 704) with Provisioning System 703, which may be an element of a wireless telecommunications network and/or may be communicatively coupled to a wireless telecommunications network (e.g., with which Backup UE 101 is also associated). For example, Provisioning System 703 may be, may include, or may be communicatively coupled with, a HSS, UDM, and/or other device or system that maintains subscription information associated with UEs and/or subscribers.

The initializing and/or provisioning may include indicating, to Provisioning System 703, that Replacement UE 701 is a replacement for Backup UE 101. For example, the initializing or provisioning may include providing an account or user identifier, indicating that Backup UE 101 and Replacement UE 701 are both associated with the same account or user. In some embodiments, Initiating UE 103 may provide (not shown) an indication to Provisioning System 703 and/or Remote Backup System 105, that Replacement UE 701 is a replacement for Backup UE 101. While not described in detail here, Provisioning System 703 and/or Remote Backup System 105 may authenticate Replacement UE 701 to verify that Replacement UE 701 is authorized to receive backup data associated with Backup UE 101.

Based on the initialization and/or provisioning, Provisioning System 703 may instruct Remote Backup System 105 and/or Backup Data Repository 109 to provide (at 710) backup data, from UE 101, to Replacement UE 701. For example, Provisioning System 703 may instruct Remote Backup System 105 to provide the backup data, which may in turn instruct Backup Data Repository 109 to provide the backup data, and/or may retrieve the backup data from Backup Data Repository 109 and provide the backup data to Replacement UE 701 (not shown). Additionally, or alternatively, Provisioning System 703 may instruct Backup Data Repository 109 to provide the backup data to Replacement UE 701.

Additionally, or alternatively, Provisioning System 703 may instruct (at 708) Replacement UE 701 to obtain backup information, associated with Backup UE 101. Based on this instruction, Replacement UE 701 may obtain (at 710) the backup data from Backup Data Repository 109. In some embodiments, Provisioning System 703 may provide authentication information (e.g., an authentication token, an authentication key, etc.) to Replacement UE 701, Remote Backup System 105, and/or Backup Data Repository 109, which may be used to authenticate a request from Replacement UE 701 for the backup data associated with Backup UE 101.

Once the backup data is received (at 710) from UE 101, Replacement UE 701 may restore (at 712) the backup data by installing, storing, etc. some or all of the received backup data. In this manner, Replacement UE 701 may have settings configured, may have user data (e.g., pictures, videos, music, documents, etc.) stored on local storage, may have user accounts already configured, and/or may otherwise be configured to provide the same or similar user experience as Backup UE 101. Further, this configuration may occur at the time of initial provisioning (e.g., by a vendor, carrier, etc.) prior to receipt by the user, thereby minimizing the amount of user interaction needed for data from Backup UE 101 to be restored, installed, configured, etc. on Replacement UE 701.

FIG. 8 illustrates an example process 800 for initiating a remote backup. In some embodiments, some or all of process 800 may be performed by Remote Backup System 105. In some embodiments, one or more other devices may perform some or all of process 800 (e.g., in concert with, and/or in lieu of, Remote Backup System 105).

As shown, process 800 may include registering (at 802) Backup UE 101 and one or more Initiating UEs 103. For example, as described above, Remote Backup System 105 may receive identifying information associated with Backup UE 101 and Initiating UE 103, and may authenticate Initiating UE 103 as being authorized to initiate remote backups for Backup UE 101.

Process 800 may further include receiving (at 804) a remote backup request from Backup UE 101. As described above, the remote backup request may include identifying information for Backup UE 101, a network backup policy, types of data to back up, etc. In some embodiments, the remote backup request may include authentication information, such as a token received by Initiating UE 103 during the registration process (at 802).

Process 800 may further include authenticating (at 806) the remote backup request. For example, the remote backup request may include a token and/or other suitable authentication information, based on which Remote Backup System 105 may verify that Initiating UE 103 is authorized to request a remote backup of Backup UE 101.

Process 800 may also include providing (at 808) a backup instruction to Backup UE 101. Based on this backup instruction, Backup UE 101 may initiate a backup according to the indicated network policy. In some embodiments, as discussed above, Backup UE 101 may override the network backup policy based on being in “lost” mode.

FIG. 9 illustrates an example process 900 for performing a device backup when Backup UE 101 is in “lost” mode. In some embodiments, some or all of process 900 may be performed by Backup UE 101. In some embodiments, one or more other devices may perform some or all of process 900 (e.g., in concert with, and/or in lieu of, Backup UE 101).

As shown, process 900 may include receiving (at 902) a remote backup request. The remote backup request may include a network backup policy (e.g., as specified by Initiating UE 103).

Process 900 may further include determining (at 904) that Backup UE 101 is in “lost” mode. For example, Backup UE 101 may have been placed in “lost” mode prior to receiving (at 902) the remote backup request.

Process 900 may additionally include overriding (at 906) a configured network backup policy based on the determination that Backup UE 101 is in the “lost” mode. For example, as discussed above, based on Backup UE 101 in “lost” mode, the requested data associated with Backup UE 101 may need to be backed up, regardless of the network backup policy specified by Initiating UE 103. In some embodiments, Backup UE 101 and/or Remote Backup System 105 may notify Initiating UE 103 that Backup UE 101 is in “lost” mode, and may request permission to override the network backup policy specified in the remote backup request. In such embodiments, Backup UE 101 may override the specified network backup policy upon receipt of confirmation from Initiating UE 103 that the network backup policy may be overridden.

Process 900 may also include outputting (at 908) the backup data, associated with Backup UE 101, using any available network. For example, even if the network backup policy restricts a given type of network (e.g., Mobile Network 501), the restricted network may be used when the network backup policy is overridden.

The software instructions stored in memory 1130 may cause processor 1120 to perform processes described herein. Alternatively, hardwired circuitry may be used in place of or in combination with software instructions to implement processes described herein. Thus, implementations described herein are not limited to any specific combination of hardware circuitry and software.

The foregoing description of implementations provides illustration and description, but is not intended to be exhaustive or to limit the possible implementations to the precise form disclosed. Modifications and variations are possible in light of the above disclosure or may be acquired from practice of the implementations.

For example, while discussed in the context of a “lost” mode, in some embodiments, similar concepts may apply for UEs that have some other type of status that is associated with inaccessibility by a user associated with respective UEs. For example, a UE may be set to “damaged” mode (e.g., by receiving an instruction or notification, similar to the enabling of “lost” mode discussed above). For example, a user may set the UE to “damaged” mode if a screen, input device, or other component of the UE is damaged or unusable. In some embodiments, the UE may automatically set itself to “damaged” mode if one or more sensors of the UE indicate that the UE is, or may be, damaged. For example, if an accelerometer or other motion detection component of the UE detects that the UE has been dropped, has experienced an impact of at least a threshold amount of force, etc., the UE may set itself to “damaged” mode. As another example, if a moisture sensor of the UE detects that the UE has been exposed to a threshold amount of moisture, the UE may set itself to “damaged” mode. As another example, some other suitable sensor or mechanism may indicate that a screen of the UE has been cracked or otherwise damaged, based on which the UE may set itself to “damaged” mode. When in the “damaged” mode, a remote backup may be initiated by an initiating device, and/or the UE may automatically initiate a backup, such that data stored on the UE may be recovered at a later time.

While series of blocks and/or signals have been described above (e.g., with regard to FIGS. 1-3, and 5-9), the order of the blocks and/or signals may be modified in other implementations. Further, non-dependent blocks and/or signals may be performed in parallel. Additionally, while the figures have been described in the context of particular devices performing particular acts, in practice, one or more other devices may perform some or all of these acts in lieu of, or in addition to, the above-mentioned devices.

The actual software code or specialized control hardware used to implement an embodiment is not limiting of the embodiment. Thus, the operation and behavior of the embodiment has been described without reference to the specific software code, it being understood that software and control hardware may be designed based on the description herein.

Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of the possible implementations. In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. Although each dependent claim listed below may directly depend on only one other claim, the disclosure of the possible implementations includes each dependent claim in combination with every other claim in the claim set.

Further, while certain connections or devices are shown, in practice, additional, fewer, or different, connections or devices may be used. Furthermore, while various devices and networks are shown separately, in practice, the functionality of multiple devices may be performed by a single device, or the functionality of one device may be performed by multiple devices. Further, multiple ones of the illustrated networks may be included in a single network, or a particular network may include multiple networks. Further, while some devices are shown as communicating with a network, some such devices may be incorporated, in whole or in part, as a part of the network.

To the extent the aforementioned implementations collect, store, or employ personal information provided by individuals, it should be understood that such information shall be collected, stored, and used in accordance with all applicable laws concerning protection of personal information. Additionally, the collection, storage, and use of such information may be subject to consent of the individual to such activity (for example, through “opt-in” or “opt-out” processes, as may be appropriate for the situation and type of information). Storage and use of personal information may be in an appropriately secure manner reflective of the type of information, for example, through various encryption and anonymization techniques for particularly sensitive information.

No element, act, or instruction used in the present application should be construed as critical or essential unless explicitly described as such. An instance of the use of the term “and,” as used herein, does not necessarily preclude the interpretation that the phrase “and/or” was intended in that instance. Similarly, an instance of the use of the term “or,” as used herein, does not necessarily preclude the interpretation that the phrase “and/or” was intended in that instance. Also, as used herein, the article “a” is intended to include one or more items, and may be used interchangeably with the phrase “one or more.” Where only one item is intended, the terms “one,” “single,” “only,” or similar language is used. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
